IMPROVEM ENT IN GANG-FLOWS.

Specification forming part of Letters Patent No. 2l9,565, datedSeptember 16, 1879; application filed February 18, 1879.

To all whom it may concern:

Be it known that I, Josnrn BELDUKE, (in French, BoLDUo,) of the city andcounty of San Francisco, and State of California, have in vented certainnew and useful Improvements in Gang-Flows; and I do hereby declare thatthe following is a full, clear, and exact de scription thereof,reference being had to the accompanying drawing.

My invention has reference to that class of gang-plows in which theforward ends of the plow-beams are loosely attached torearwardprojecting arms on the axle of the truck or wheel portion, sothat, the plows are dragged behind the truck. I

The accompanying drawing represents a pespective of the plow.

Referring to the drawing, A represents the axle of the truck, and B Bthe bearing-wheels. The axle A is strc ight, and the furrow-wheel B islarger in diameter than the land-wheel, so that when it is moving in thefurrow the axle will be horizontal; but when the truck is moving onlevel land the axle will be slightly inclined, but not sufficient to beparticularly noticeable. The wheels will therefore require no specialadjustment to adapt them for plowing or moving on level land.

0 D are two rearward-projectin g arms, which are arranged to slide uponthe axle, and be adjusted by the means hereinafter described.

It will be noticed that the lug or arm D on the side next to the land islonger than the arm C on the furrow side. This is an important feature,as will soon be seen.

Where two or more plows are used in a gang the beam of the plow next tothe furrow-wheel is shortest, and the plow is'nearest to the axle, andthe other plows are set successively farther back, so that each willturn the soil into the furrow of the plow in advance of it. Thisnecessitates the employment of a longer beam for each succeeding plow.Heretofore the beams of all the plows were rigidly connected together,and the forward ends of all the beams were attached to a single rod orbar, which connected the arms C D in one line. When this was the casethe forward ends of all the beams were lifted correspondingly when theaxle was rotated by means of the lever F, and

as the plows were at unequal distances from the axle the points of theplows farthest from the axle would .not be raised as high as the pointsof those nearer the liftingpoint.

The object of my improvement is to equalize the lifting of the pointsofall the plows, so that when it is desired to run the plow out of theground a single motion throws all the points up at once to a uniformangle, and the plows run out of the ground without applying power tolift them bodily. To do this I make the beam of each plow separate fromthe others, and then connect them together by means of two crank-shafts,or by means of one crank-shaft near the middle of the beams, and a pinand slot at their rear ends. attach the forward end of the short beam tothe short arm C, and the forward end of the long beam to the long arm D,so that the greater distance of the plow with the long beam from thelifting-point is compensated for by a long lift.

In the drawing, G is the short beam of the furrow-plow. The forward endof this beam is attached loosely to a rod or bolt, h, which extends fromthe arm C to the arm D.

I is the long beam of the rear plow, and its forward end is looselyattached to a bolt at the end of the long arm D. An angular bracebar, j,extends from the rear end of the short plow-beam G back to the rear endof the long beam I and is attached to it by a pin-and-slot connection,so that the two beams will have a limited motion independent of eachother. Each beam has a bridge-shaped brace, K, on the inside, nearlyopposite the middle of the long beam. A crank-rod, L, connects the twobeams, being supported in the beams and braces, as shown. This.crank-rodmight be dispensed with, and a single loose fastening used forconnecting the rear ends of the beams.

Now, when the axle is rotated by means of the lever F, so as to raisethe arms 0 D, the forward end of the long beam will be raised thefastest, because it is attached to the long arm 1), while the crank-rodL rotates correspondingly, and preserves the position of the beams, thusraising the points of the plows to the same height, if the difference inthe lengths of the arms is correctly proportioned.

To adjust the plows to or from the land I have a lug, p, on the axle,outside of the slid- I also in g arms. A set-screw, 1", screws throughthis lug, and has its end loosely fastened in the arm next to it. Bymeans of this screw I can set the arms, and through them move the beamsand plows to or from the land, as described.

I thus provide an equal movement of the plows, so that they can be runout of the ground by the forward movement, lifting the plows and theload of earth on the mold-boards.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The plow-beams GI of a gang-plow, connected by the rear angularbrace, j, with its slot-and-pin fastening, and having the bridgeshapedbraces K,-said beams and braces being connected by a crank-rod, L, andthe forward ends of the beams being connected with arms 0 D, of unequallength, substantially as and for the purpose described.

2. The axle A, with its arms 0 D of unequal length, in combination withthe plowbcams G I, which are loosely connected at the rear ends,substantially as and for the purpose described.

In witness whereof I hereunto set my hand and seal.
